The Story: As Hitler's armies invaded Europe and the value of human life diminished, a small team of scientists at Oxford University made the world's first antibiotic using mouldy fruit; penicillin, one of the greatest discoveries in the history of medicine. As news of the strange brown powder leaked out to the press, wartime Britain looked for a hero to shower with academic and civic honour. But instead of the Oxford team they chose Alexander Fleming who had given up the idea fourteen years earlier. How it happened is a fascinating story of a group overcoming wartime scarcity, personal conflicts, marital infidelity and medical half-truths, and a sobering lesson in the long-term damage done to truth by wartime propaganda.
